Abstract: CO2 pricing enables building owners to benefit from reduced emissions. Changing power plant mix leads to dynamic CO2 factors and price signals that PV-battery systems can exploit. The system's size and CO2 prices influence profitability. So far, no study exists assessing CO2 pricing's influence on PV-battery systems' optimal sizing and operation. We, therefore, investigate the interaction of PV-battery sizing and operation with CO2 pricing and combine Design of Experiments with MPC. For a CO2 price of 100 €/t, the cost-optimal design decreases emissions by 79.7 %. Furthermore, high CO2 prices yield large PV and medium battery sizing.
